1. 1. The Metallicity Structure of the Milky Way Halo II : Characterising the distant halo substructure

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Sammanfattning : The Milky Way galaxy, like all spiral galaxies, is surrounded by a roughly spherical distribution of stars called the halo. The halo was largely formed when the galaxy merged with smaller galaxies. LÄS MER

3. 2. The consequences of dwarf galaxies colliding with the Milky Way

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Ryan Skeoch; [2014]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : I simulate the collision of satellite galaxies with the Milky Way and observe the effects that this has on the orbits of the globular cluster populations within both the Milky Way and the satellite galaxies. This is done in order to investigate whether some of the Milky Way's globular clusters could have been donated from satellite galaxies which have been tidally stripped, since it is believed that the Sagittarius dwarf spheroidal galaxy is being tidally disrupted and that some of its globular clusters have been tidally stripped from it (such as Pal 12 and NGC 4147).
